Example text

Clearances as low as one-half meter are suitable in this position, provided the observer is standing and not bent over. 3). Lower-angled Newtonians often need a bent or seated position on the part of the observer, and possibly the accommodation of an observing chair, which will require more clearance. Refractors on German Equatorials present the observer with the same awkward positions. 1. Mid-construction test: Refractor fits under closed roof when rotated completely horizontal. If calculations had been incorrect, the pier or cement base pedestal would have to be shortened.

4). (k) generally easier to accept on a re-sale of the property because it masks as a shed. (l) easier to construct than a domed observatory. (j) usually less expensive to build than a domed observatory (aluminum domes are high in price). (n) no special tools required (except for the welding of track – best contracted out). Questions to Ask Before You Begin 1. Do you have sufficient space to build an observatory? (the roll-off roof type requires more space than a domed observatory requiring a roll-off gantry frame).

In my own case, I used a column of concrete in a sono-tube to about one-half the height of the proposed pier above the floor, completing the rest with the same length of equal diameter thick-walled aluminum pipe. I machined heavy 1½″ thick aluminum flanges as caps over each end, recessed to fit into the pipe, and machine-bolted into the tapped flanges through the pipe walls. The flanges were pre-drilled to fit the bolts protruding from the concrete pier base on the bottom end (requiring a template to be made first in heavy card), and to match the bolt circle of the telescope mount on the top end.
